withdraw what?? crypto?? There's no profit to doing that?
have to buy at a foreign exchange and sell at a Korean exchange to make a profit... Do You know the definition of crypto arbitrage, right??
Then if you find a partner, how do you give money to your partner if making a withdrawal doesn't bring a profit?

I can trade on the Korean exchange, so I sell crypto on Korean exchange and then exchange the money into dollars and send it to my partner's bank account. Do you understand?
One of my high school friends said he was in the US, so I'll have to contact him. Thanks for the comment
